Abstract: 본 발명은 무선 차량 호출 방법과 장치에 관한 것이다. 차량군을 관리하는 시스템에서 차량의 위치에 따라 선택적으로 차량 호출 등의 지령을 내려야 한다. 종래의 기술로는 이를 구현하기 위해 차량의 위치를 주기적으로 센터에 무선 전송하여야 했으나, 차량의 대수가 많아질수록 이에 비례하여 무선 전송 회수가 증가하여 무선 망의 부하를 크게 할 뿐 아니라 통신비용 또한 증가하여 이를 효율적으로 구현하기 어려웠다. 본 발명은 무선호출망 등의  저렴한 단방향 방송형 무선망으로 모든 차량에 지령을 내리되, 지령문을 수신한 차량이 자신의 위치에 선택적으로 호출에 응답하도록 하였다. 이렇게 함으로서 차량에서 주기적인 위치 전송의 필요성을 제거하였으므로 대규모 차량군에서도 선택적 차량 호출이 가능하도록 하였다. 본 발명의 부가적인 효과로 각 차량의 위치가 센터에 노출되지 않게 되기에 운전자 개인 정보가 보호되는 장점이 있다.

Abstract: PURPOSE: A method for manufacturing a semiconductor device is to provide a transistor having a gate length smaller than a critical dimension of a gate mask, and to guarantee a reduced gate channel length margin by forming a channel of a round shape. CONSTITUTION: A first and a second insulating layers are evaporated on a substrate(31). A partial region of the first and the second insulating layers are etched to form a trench on the substrate. A third insulating layer is formed on the surface of the trench in the substrate and on an inner surface of the first and the second insulating layers. A first sidewall spacer is formed on an inner surface of the third insulating layer. A thermal oxidation layer is formed on the substrate between the first sidewall spacer. The first sidewall spacer is eliminated. First impurity ions are injected into the substrate by using the thermal oxidation layer. A second sidewall spacer(37) is formed on an inner surface of the third insulating layer on both sides of the thermal oxidation layer. The thermal oxidation layer is eliminated to expose the substrate of a round shape. A gate insulating layer(38) is formed on the exposed substrate. A gate electrode(39) is formed on the gate insulating layer between the second sidewall spacer. After the second insulating layer is eliminated, a second impurity region is formed in the substrate on both sides of the second sidewall spacer and third insulating layer excluding the gate electrode.

Abstract: PURPOSE: A stacked structure of an electric double layer capacitor is provided to obtain the required voltage by adopting a simple stacked structure of the electric double layer capacitor. CONSTITUTION: A stacked structure of an electric double layer capacitor comprises the first device including a (+) lead line(20) formed at a side of an upper electrode(16) and a (-) lead line(22) formed at one end portion of a lower electrode(18). A separator(24) is inserted between the upper electrode(16) and the lower electrode(18). The second device(14) has a (+) lead line(20) formed at a side of the upper electrode(16) and a (-) lead line(22) formed at an end portion of the lower electrode(18). The second device(14) is positioned below the first device. The the first device is welded to the second device(14) in series. The first and second devices are contained in a case and the case is sealed.
